Description
The PI5A317A/381A/319A are analog switches designed for single-
supply operation. These high-precision device is ideal for low-
distortion audio, video, signal switching and routing.
The PI5A317A is a single-pole single-throw (SPST), normally
closed (NC) switch. The PI5A318A has the same pinout but is a
single-pole, single-throw (SPST, normally open (NO) function. The
PI5A319A is a single-pole, double-throw (SPDT) switch
Each switch conducts current equally well in either direction when
on. When off, they block voltages up toVCC.
The PI5A317A/381A/319A are fully specified with +5V and +3.3V
supplies. With +5V, theyt guarantee <10Ω on-resistance. On-resis-
tance matching between channels is within 2Ω. On-resistance
flatness is less than 5Ω over the specified range. This switch family
also guarantees fast switching speeds (t_ON < 20ns).
These products are available in a 8-pin narrow body SOIC, and
PDIP packages for operation over the industrial (-40^oC to +85 ^oC)
temperature range.
